Constant wattage heat tracing cables advantages.
Parallel resistance heating cable.
Constant wattage heating cables as their name suggests are designed to deliver the same power output irrespective of pipe temperature.
Where resistance of the material increases as the operating temperature rises a reduction of heating power occurs.
Single end power input.
The parallel resistance configuration allows the cable to be cut to length and terminated in the field with easy to use thermon supplied kits.
Measure the resistance of each cable individually and investigate deviations in resistance between parallel conductors.
Apart from the connections some of these parallel electrical heating cables can be immersed into fluids.
Fp parallel resistance constant watt heating cables are de signed to provide freeze protection or process temperature maintenance to piping tanks and equipment.
It has an aluminium outer.
Our powerheat aht is a unique patented high power high temperature constant wattage cable.
Constant power output per meter.
What are self regulating or power limiting heating cables.
Verify uniform resistance of parallel conductors using a low resistance ohmmeter.
The following tests are type test of electrical power cable.
Given below are various kinds of tests that are conducted on cables.
We produced the world s first parallel resistance cut to length heating cable in 1978.
Heating cables type elsr n self regulating heating cable up to 80 c 8 9.
